What is columbite ore?
Columbite, also called niobite, niobite-tantalite and columbate [(Fe, Mn)Nb. 2O. 6], is a black mineral group that is an ore of niobium. It has a submetallic luster and a high density and is a niobate of iron and manganese. This mineral group was first found in Haddam, Connecticut, in the United States.
Where can the largest deposit of bitumen be found in Nigeria?
Agbabu
Nigeria is greatly endowed with large deposit of natural bitumen at Agbabu, Ondo State. The country was reported to have a proven reserve of about 42.47 billion tonnes of bitumen, a quantity which is estimated to be second largest in the world but yet to be explored for economic purposes.
Where is tin found in Nigeria?
The tin deposits are distributed sporadically over a wide area of over 10,000 square miles at a height of from 2,000 feet to 4,000 feet above sea-level, the most important deposits, however, occurring in the Bauchi Plateau, most of which is at the higher elevation.

What is tantalite used for?
Tantalite is the most widespread tantalum mineral and makes for an important ore of the industrially useful metal. Tantalum is used in alloys for strength and higher melting points, in glass to increase the index of refraction, and in surgical steel, as it is non-reactive and non-irritating to body tissues.
What is the difference between tantalite and tantalum?
As nouns the difference between tantalite and tantalum is that tantalite is (mineralogy) a dark-brown mineral that is an ore of tantalum and niobium, of the chemical formula (fe]], mn) ta2[[oxygen|o6 while tantalum is a metallic chemical element (symbol ta) with an atomic number of 73.
How do you mine tantalite?
Most tantalum mines are open pit; some are underground. The process of mining tantalum involves blasting, crushing and transporting the resulting ore to begin the process of freeing the tantalum. The ore is then concentrated at or near the mine site, to increase the percentage (by weight) of tantalum oxide and niobium.
What is coltan worth?
1kg costs around $100, but prices have historically been as high as $600 per kg. A Congolese Coltan miner can earn up to $200 per month.
